Figure 1: A Typical Vertical Spindle Pulverizer installed within the pipes are used to adjust the individual primary air flows. While the use of orifices in the coal pipes can be an effective way of balancing air flow rates, evidence from field measurements suggests the orifices have little effect on distribution
The coal pulverizer is applied to crush the coal to an average size of 0.074 mm powder. At the entrance of coal pulverizer, the temperature would be between 160 C to 393 C. The blowing speed is 50 to 55 m/second. When the high Cr cast steel (48-58 HRC) liner plate is used, the service life is 1.5 to 2 years, but spalling would be an issue.
